I foolishly ejected the disk while it was still mounted and flipped the write protect tab - and lo!: cat > foo.tmp failed and got stuck In fact nothing could kill this process now listed as D. In fact the drive now can't be mounted or unmounted. I did some reading and it appears that a forced mount or lazy mount might work - but umount -f fails with: umount2: Device or resource busy umount: /dev/hdc: not mounted umount: /media/cdrom: Illegal seek I'm sure that if I reboot - all will be fine... But we try to avoid rebooting Seems like: - one shouldn't be able to eject media that's mounted - if one does - it shouldn't take down the device - if it does take down the device - it'd be nice to be able to fix it without rebooting I'll monitor the list for any questions - but feel free to email too and I'll post a summary of the answers.
